Ford, Mercedes And Nissan Ally On Hydrogen Cars

I am very unsure about the benefits of hydrogen cars – Firstly the majority of hydrogen is currently produced from natural gas which involves similar emissions to using liquid petroleum gas. If you are going to use natural gas to produce hydrogen, then you might as well use LPG which is easier to handle than hydrogen and if you intend to use a fuel cell, then reform on board or use a methane fuel cell. If you use electrolysis to generate hydrogen from wind or sun, then cycle efficiency becomes a big problem. Wind to wheel efficiency of electrolysis, (producing hydrogen) distribution – getting it to the vehicle, compression – getting it into the fuel tank and use in a fuel cell is unlikely to exceed 40%. (slightly higher if you can use the heat given off during electrolysis). This compares very badly to batteries which are nearer to 90% DC/DC efficiency or 85% AC/DC efficie...
